Abstract
The present invention concerns a Magnus rotor comprising a guide roller which is arranged at the lower outer periphery of the Magnus rotor and which bears against the Magnus rotor in play-free relationship, a walkway surface arranged beneath the guide roller, and a cover which covers the guide roller and the walkway surface. In an opened condition the cover exposes the guide roller and the walkway surface so that a person on the walkway surface can perform working operations at the guide roller.
